Abstract
Optical assemblies for use in medical or other devices so as to image an object under examination onto an image sensor include a plurality of lens elements that can be retained in lens barrel. The lens elements and the lens barrel can be sealed with a compressible gasket. In one example, at least one lens element is made of an injection-moldable plastic and at least one lens element is made of a relatively dispersive optical glass. A lens barrel diameter or lens diameter can be selected to permit access to the object under examination with surgical or other tools. Aperture plates can be situated so as to reduce flare in the object image.
